Abstract (en)
[origin: US6437517B1] Power source systems implementing methods for reducing vertical segregation (color mixing) in a long and thin high intensity discharge lamp are disclosed. Each system provides a current frequency signal to the lamp that excites an azimuthal acoustic and longitudinal acoustic combination mode of the lamp whereby color mixing within the lamp can be achieved. Each system further adjusts the current frequency signal as needed to stabilize color mixing within the lamp.
